Answer:
function as support cells
Explanation:
Neurons are structural and functional units of the nervous system. They are specialized cells that carry impulses from one part of the body to another. There are three main types of neurons in mammalian body. These are motor, sensory and intermediate neurons.
Answer: B- Bacteria
Explanation: Bacteria are infinitesimal organisms that have single cells that grow in different atmospheres. They have an easily understood inside arrangement. Their cells are normally surrounded by two shielding coverings which are an external cell continuous vertical structure and a cell pliable sheet-like structure acting as a boundary inside. However, some bacteria do have a third shielding sheet furthest from the center named the capsule.
<em><u>The MC1R gene provides instructions for making a protein called the melanocortin 1 receptor. </u></em>
Explanation:
MC1R’s function-This receptor plays an important role in normal pigmentation. The receptor is primarily located on the surface of melanocytes, which are specialized cells that produce a pigment called melanin.

Explanation:
Root hairs are found in the plant it is a hair-like structure present on the surface of the root tip and Root hairs have large surface area that increase the absorption rate of water and minerals.
Water is absorbed by root hair cells through the process called Osmosis and Minerals ions is absorbed root hairs by the process called active transport.
The function of root hair is to collect the minerals and waters present in the soil and then transfer these nutrients and water through roots to different parts of the plant.
When an area is malaria-free, the HbS allele frequency is between 0 and 2.02. Thus, option "A" is correct.
<h3>How, explain your answer briefly?</h3>
In the two maps that show the allele frequency of sickle haemoglobin (HbS) and malaria endemicity in Africa, it can be seen that in the regions with no malarial outbreak or malaria-free areas coincide with the grey to lighter shades of red in the heat map of the allele frequency of HbS. The colour coding in the heat map for the allele frequency tells us that the frequencies range from 0 to 2.02 in the malaria-free areas.
Hence the answer is A)When an area is malaria-free, the HbS allele frequency is between 0 and 2.02.
